Lake Clark month by month: notes from the park service
- March: March at Lake Clark is still winter. The lake itself usually stays frozen until April, and in winter parts of the park can be reached only by planes on skis, weather permitting; ice conditions decide whether a float or ski plane can land at all.
- April: April is usually when the ice on Lake Clark melts, the park says, after a freeze that typically begins in November. That changeover matters, because ice conditions decide whether planes on floats or skis can land.
- May: May at Lake Clark is the lead-up to the main season: most visitors come between June and October, when it is warmer and more lodging, transportation and guide services operate. Frost and snow are still possible until early June.
- November: November is when Lake Clark typically starts freezing, the park says, and from then on, ice conditions decide whether planes on floats or skis can land. Port Alsworth, in the interior, averages lows near 1°F by January, and the record is -55°F.
